Question

7 (2 + z)(2)

Explanation:

Step1: Apply distributive property

The distributive property states that \(a(b + c)=ab+ac\). Here, \(a = 2\), \(b=2\), and \(c = z\). So we have \((2 + z)(2)=2\times2+2\times z\).

Step2: Simplify each term

Calculate \(2\times2 = 4\) and \(2\times z=2z\). Combining these, we get \(4 + 2z\).

Answer:

\(4 + 2z\)
